I still stand by the ground that Opo might not be ****ting with us.
He was part of the Fate/Mafia, so he knows that making an invincible claim without any way to prove it is basically asking for death.
That's how the town won that game, actually, since Erureido's claim was too ridiculous. Granted, the stuff about him reflecting night actions was true, but him bringing anyone who voted for him to the grave alongside him was too broken and ridiculous to be taken seriously.
The DBZ mafia was also won by the town (and me) because of a fakeclaim that was never proven.
Guys, Opo isn't stupid enough to make dumb mistakes like that.
